Other Safety Guidelines

Aircraft
Regulations prohibit using your mobile
device while onboard an aircraft. Switch
off your ZenFone 4 before boarding
an aircraft or turn off the wireless
connection.

Blasting areas

To avoid interfering with blasting
operations, turn your ZenFone 4 off when
in a blasting area or in areas posted:
"Turn off two-way radio." Obey all signs
and instructions.

Potentially explosive environments

Turn your ZenFone 4 off when in
any area with a potentially explosive
environment and obey all signs and
instructions.
Sparks in such areas could cause an
explosion or fire resulting in bodily injury
or even death.
Areas with a potentially explosive
environment are often, but not always,
clearly marked. They include fuelling
areas such as gas stations, below decks
on boats, fuel or chemical transfer or
storage facilities, vehicles using liquified
petroleum gas (such as propane or
butane), areas where the air contains
chemicals or articles, such as grain, dust,
or metal powders, and any other area
where you would normally be advised to
turn off your vehicle s engine.
Choking
Keep your ZenFone 4 away from children
as the SIM card and other small parts
present a choking hazard.
